High-performance Dynamat Xtreme is a patented, lightweight elastomeric butyl and aluminum constrained-layer vibrational damper. It's lighter than Dynamat Original, requires no heat to apply, and is coated with aluminum for high temperature areas such as firewalls and floors. Best of it all, it's four times more effective than original Dynamat in reducing noise!

Features

Xtreme: Dynamat Xtreme provides 4 times the damping efficiency
of Original Dynamat, the conforming ability of Premium Dynamat, and the radiant
energy reflection of Super Dynamat. Dynamat Xtreme has an aluminum layer for high
temperature areas.

Mounting: Mount the speaker as you normally would, Dynamat
Xtreme will create a seal and damp the door panel to maximize the speaker's
performance.

Excess: Use any excess Dynamat Xtreme to attach to the speaker
basket, thus cutting down on resonance.

Adhesive: There is a high tack permanent adhesive with a peel
off plastic liner on the back of the Dynamat Xtreme.

Sizing: The material cuts easily with scissors or a razor
knife. Dynamat Xtreme will increase the speaker's mounting height and reduce
mounting depth by approximately 0.085". It is typically used to install
two speakers for maximum performance.

Installation

Clean mounting surface (bare metal)

Using a razor knife or scissors cut Dynamat Xtreme
to the desired size

Apply Dynamat Xtreme, centering the sheet over the
speaker opening

Apply pressure, working Dynamat Xtreme into the
contours of the door panel

Using speaker hole as a guide, cut away center
portion of sheet

Dynamat-2009 Ford F150

Never used this product before, but when installing my new speakers in all 4 doors of my 2009 Ford F150 SuperCrew, I decided that what this product claimed to do sounded like it made since to use. I must say that it did everything it claimed to do. It was easy to use and made a very solid, and vibration proof mounting surface. It isolates the speakers from direct contact with the metal doors. I am glad I purchased.

Amazing difference...

Replace stock speakers in the rear cargo area of a 2003 Nissan Xterra. The new speakers caused a horrible rattling sound as the bass vibrated the metal quarter-panels. I installed Dynmat against the quarter-panel behind the mounted speaker and it completely corrected the problem. I also cut pieces of Dynamat around the mounting screw holes of the speakers for added protection against vibration. This stuff is amazing and I highly recommend it.

Pros:Excellent results

Cons:A little costly for what it is, but I would purchase this again in a heartbeat.

What needs to be said?

We used the Dynamat 10415 in our 2004 Altima front doors to try and cure vibrations and rattales we were getting. Needless to say I am a big fan of using Dynamat - so we installed on sheet per door and it made a huge difference in sound quality. No more vibrations, no more rattles. Super easy to work with. Great product at a fair price. Do not install without if you want to squeeze every last bit of performance out of the speakers you are installing.

Great product

I have used this product in all of my vehicles to help insulate the sound of my subwoofers and to reduce rattles. It does not eliminate all of them, but close to 95% success rate. I would recommend Dynamat to anyone that is interested in sound deadening materials. Great Brand!!

Firm believer in usage of Dynamat

This stuff makes all the difference. Can get a little expensive, but seriously worth the money. If you are going to pay to have new speaker in your car, spend a little extra and make sure your panels and/ or doors don't vibrate.

first time buyer off online

This was a surprise I ordered it thinking I will try it out but did not expect that big of a change in sound, and noise form my vehicle to be reduced as well as it was. thank you for suggesting this product.

Pros:easy to install and a very economical enhancement with very good results

a MUST for any vehicle

I've used Dynamat in all of my cars, and will only buy from Crutchfield. If you're new to Dynamat, you should seriously consider making the purchase. Not only will it greatly improve the quality of your soundsystem, but it will greatly cut down the road noise coming through your doors. I recommend putting sheets on both sides of your front doors, as well as sheets in the back. If you're running a subwoofer in your trunk, consider getting a Dynamat trunk kit as well for your vehicle!

Pros:Unparalleled ability to block out road noise and support your speakers in getting their full potential.

Cons:Can be a little tricky on your first installation, but after that, it's a breeze!

$$$$$$$$$$$$$$

Cons:In my opinion, Dynamat is taking advantage of the consumer. This product should not be as expensive as it is. Look for other alternatives that work just as well. Crutchfield should do this also...

Dynamat 10415 Xtreme Speaker Kit

Bought a pair of Infinity Reference and this dynamat. Installed without the dynamat and listened to it for a few weeks. Then I pulled it all apart and installed the dynamat. Not money well spent. The resonance went down a tad when I had the bass all the way up. But since I don't listen to music with the bass all the way up it did not matter. No noticeable improvement. Sorry guys... I imagine if you installed on the whole door it would quiet outside noise. However, this tiny square, does not cut it. More like one of those add-ons people like to tell their friends they added. Then because they spent the money they tell themselves it works. Well if I went from stock to new quality speakers with this installed immediately I probably would tell people it works. But I know better now. Having tried with and without, I would not buy this twice.

Happy Camper

Ordered some Polk Speakers for my son's Chevy Colorado and took advantage of the Dynamat 10415 special offer.

All I can say is that this stuff made a significant difference in the sound of his new speakers; especially in the bass department. Using the stock HU, he can experience the same amount of bass as my daughter's stock Nissan Sentra Audio System (which is pretty amazing for stock). There's really no need for a new HU now and a sub would be overkill.

I'm sure a "some results may vary" disclaimer is needed here, but I'm a beliver enough to order 2 more sets of the Dynamat speaker kits and will be placing them behind the 4 speakers in my own truck.

Last thing...the use of gloves suggestion is warranted. You could easily cut yourself with this stuff. Well worth the risk, but be careful.

Does the job and more

I recommend getting the door package rather than just the speaker package. I used Dynamat extreme door package on the front doors of my Honda Accord (which has aftermarket speakers and an amp.) Not only does it do the job of soundproofing (yes the car is much quieter) it is amazingly easy to put on and work with. I am so satisfied with the result I am going to do the rear doors next week. Also I must say the instructions that Crutchfield sent for removing the door panels were nothing short of excellent. Gave me the confidence to do it myself. I used a wallpaper roller wrapped with duct tape rather than the Dynamat roller. And also found that a butter knife is excellent for getting under the door panel to pop it off the tabs underneath.
To do a "perfect" job I should have removed all the bolts (electric window motor mounts) but I just didn't want to go to that extreme. Instead I just cut out a hole to expose those bolts and worked around them. Also on my Honda I used some of the old plastic to cover some of the openings and just held it down with Dynamat. Seems to work well that way. Extreme bass is solid with no annoying door vibrations and the high end is now much cleaner without that awful sharp metallic sound. Fantastic product.

Worth every penny

Wow, who would have thought these little guys would make such a big difference. At first I installed the speakers without it. There was noticeable lack of bass. Then I changed my mind and took out the speakers and slapped these guys in there. Boy what a difference in bass response. With the money I spent on the speakers these give you big bang for the buck.

The sheets are really easy to work with - very pliable, stick really well. They say to cut a hole where the speaker goes, but I thought of a trick - if you cut an "X" into the center, you can mount the 10x10 sheet and then bend back the four corners of the "X" and stick them onto the interior surface of the door cavity. Then just easily cut out where the little holes are where you fasten the speaker onto the door and you're done.

Be very careful - you're cutting/slicing aluminum, and you *will* get little cut/nicks, almost guaranteed unless you wear gloves. I had like 5 band-aids on my hands after this job - just small nicks, but you gotta just be careful. Especially in the rear I had to cut these into like 30 pieces to completely cover the metal housing which had lots of weird shapes and corners. But again - definitely worth it.

a little goes a long way

I used Dynamat around the four speakers I recently installed in my truck. The product is very easy to use (peel and stick), and it's relatively clean (the main material is like black tar but relatively easy to remove from your skin). While one can certainly use Dynamat most everywhere there is bare metal, just using it a bit around the car speakers makes a very big difference. There is much less vibration and distortion to contend with, especially with the speakers on the front doors. However if your system really pumps out a lot of power I would use Dynamat more freely.

Dynamat 10415 Xtreme Speaker Kit

Installed one piece behind each of 4 speakers -- 2 in the front doors, 2 in the rear deck. Even this small amount noticeably dampened road noise, especially with the system playing. Even at low volumes, the music comes through much clearer and less muddled by ambient noise. The sound from all 4 is now fuller, richer, more robust, and cleaner.

CAREFUL WITH THE ALUMINUM LAYER once you've made a cut -- it will slice you very, very easily. I threw on a pair of gloves for the second set after a quick first-aid job on 2 fingers.... ;-)

pretty decent

Written By matt, Michigan on Wednesday, March 21, 2007

This stuff is good. i think i had to high of expectations for it though. it gets rid of some of the smaller raddles completely, but some of the larger ones can still be heard when the volume is cranked up. good product overall though.

Works, but not as well as expected.

Written By Ryan, Kansas City, MO on Tuesday, February 13, 2007

I had this installed in all 4 corners of my 2001 Ford Explorer Sport. Install was easy. You can notice the difference in sound, but it wasn't what i expected. My expectations might have been to high, though. It makes a noticable difference but it will NOT get rid of all the raddles in your door. I also wish that it was is was more adherable to plastic. All in all it is a decent product.

get your speakers at its full potential!

Written By diluvium, SAV, GA! on Thursday, January 18, 2007

I got this kit to get rid of the vibration on my front door speakers and its the best thing youll ever buy.

check this, all those vibration noises you hear out your door speakers is actually a part of the music. when there is vibration noises thats actually your bass notes trying to come out of your speaker. all of the noise frequencies under 100hz (BASS notes) will sound distorted if vibration noises occurs, so with dynamat your trying to get rid of that vibration to get the correct noise to your ears!

results: CLEANER BASS. all the vibration noise that is now dampened becomes in an actual music note in the songs; meaning CLEARER SOUND and noticable music notes you would not hear cause of the vibration.

theres only 1 thing wrong (1 star down) with this dampener sheets period, they are NOT WATERPROOF! because the sheets has aluminum metal on top, CONDENSATION occurs easily through cold weathers!!! i am unsure if this problem will wear or damage your speakers but those dynamat sheets hold alot condensation!! BE AWARE!

If your serious about sounds you have to Dynamat

Written By medfordpoker, Medford, MA on Friday, November 10, 2006

Dynamat is a must when your taking the time to put new speakers in or if you just added a sub woofer. I wish I could give a good analogy to describe how much better music sounds when it is properly dampened.

I decided to upgrade my 2006 Dodge Charger with Premium MQ Quarts, Alpine amps and head unit and a JL Audio Sub but after it was installed it sounded good..way better than the factory unit, but something was missing. So I asked my local audio installer and they said I should (actually demanded) that I dynamat the front and rear speakers with the 10 X 10 speaker sheets. So one saturday I opened up the doors and took off the rear dash unhooked the spears and put the dynamat on. Overall it took 2 hours start to finish. Was it worth it?....YES!!!!. I would have never thought 4 pieces of dampening could make so much difference. The mid range sounds so clear that I was able to turn my volume up 4 more nothces (from 21 to 25)!! Since the speaker kit worked so well I bought the trunk kit and put that in to. I was even more impressed with those results, my trunk and rear view mirror barely rattle anymore. I found the trunk kit to be small for my car so I bought 2 more sheets and now every inch of the trunk is covered and I couldn't be happier with the results. For around $200, installing dynamat made my car sound better than I could have ever imagined.

Good Stuff

Written By Jamie, Baltimore, MD on Monday, October 16, 2006

Installed four new speakers with my factory stereo and the rear roof speaker trim rattled like crazy. Put a 10x10 sheet of dynamat on the metal roof behind each speaker and it solved the problem. Made the speakers sound better in general also. Worth the price to fix the problem.

Dynamat 10415 Xtreme Speaker Kit

I bought two speaker kits and put them around the speakers in my doors. They do not shake or rattle. The bass is actually very clean and tight, the way it's supposed to be. Eventually I'm going complete my Jeep Liberty and put it under my hood, on the fire wall, on my floor, on my hatch, and finish my doors. I can only imagine how my music is going to sound after that. Not to mention how much of a reduction in road noise I will notice.

It is very easy to install, especially the Xtreme. The price is a little high but you can do your entire car for $150. Again, great product.

Deffinatly get this dynamat if you are installing a powerful system!!

this dynamat is a must if you are installing a powerful system, i installed it around all 4 speakers and all around the hatch area where my sub is at now, it makes all the difference in the world, NO BAD VIBRATIONS On your car with this stuff, Kinda expencive, but MOST DEFFINATLY worth every penny!! GET IT FOR SURE!! Makes the system sound even better!!

Great sound and value

My son just purchased a newer car, a 2002 Pontiac Sunfire and the sound system it came with was, well, awful. We sat down together and planned a system and since he was on a budget we decided we would go with our house brand Sound Ordnance for most of it, and we are not disappointed.
We installed the P65-C in the rear deck using the SA69 6X9 adapter. We then installed the P-40 in the front doors with fabricated brackets we made from the 12x12 sheet of ABS #1208900903 and then used the Dynamat #15410415 to seal it all up and add sound deadening to the doors.
We chose the JVC KD-R950BT for the Bluetooth and the generous power the internal amplifier has, plus the abundant color choices made it easy to match the red backlighting in the Pontiac. We needed bass so we used the Sound Ordnance B-24 and the Rockford Fosgate #575P500X1B we had from his previous vehicle and connected it using the EFX 8 gauge wiring kit #142PA8.
We spent a Sunday working on this project and have to say it exceeded my expectations on sound. It sounds clear, the bass hits as hard as you want and the total price was well within his budget. This is a great system and it was also a great day spent with my son.
